The Institute of European Studies and the Faculty of Security Studies are pleased to present to our public a translation of a very solid Practical Guide to Counterintelligence Work. The manuscript of the Soviet expert Valery Mikhailovich Zemlyanov was published in 2003 in Minsk and emphasizes the corporate practice of counterintelligence protection. But it is a general practical guide for a man who has extensive experience working in state counterintelligence systems. There are no such publicly available practical handbooks on Serbian market, so this translation will be useful both to researchers and students dealing with issues of general security, as well as to workers in security services as well as to an increasing number of employees in the sector of private security and private counterintelligence protection.
